9 6 Posi-Lock TM System Operation The Posi-Lock TM system provides an easy to use, accurate tool alignment system. These instructions explain the operation of each component. System Breakdown 1. Posi-Lock Post. 2. Posi-Lock Head. 3. Clamp Wedge. 4. Adjusting Screw. 5. Hold Down Screws. 6. Locking Screws. 7. Tool Clamp Screws. 8.T Nuts. 9. Dowel Pin. Initial Assembly Each post (1) arrives with a wedge clamp (3) and locking screws (6) attached. A dowel pin (9) aligns the wedge to stop vertical movement. The hold down screws (5) are attached to the T nuts (8). The heads (2) have the adjusting screw (4) assembled, along with the tool clamp screws. To setup a post to a head, remove the adjusting screw from the head and loosen the locking screws on the post. Slide the head onto the clamp wedge, and replace the adjusting screw so that the flange of the adjusting screw is interlocked into the clamp wedge. This allows the adjusting screw to lift or lower the head. For odd size tools or special center heights the adjusting screw can sit on top of the wedge. To fine adjust a center height, follow these steps. 1. Loosen the top locking screw and lightly snug back down (just enough to support the weight of the head.) 2. Loosen the 2 nd screw (usually the lower screw.) 3. Adjust the tool up or down with the adjusting screw. 4. Lock the 2 locking screws in place. If the locking screws are both loosened together, the head will move easily causing erratic adjustment. If the screws are not loosened enough it is possible to bend the wedge lip or the adjusting screw. If you are setting live tools or require exact positioning of the tool, a dial indicator on a mag-base can be used to check the amount of movement.

10 Posi-Lock TM System Operation 7 Assembled View This view shows a post and a 1.5 extension head assembled. Center Height Choices On a standard 1.5 post, the ranges of center heights are shown below. 1/2" tool 1/2" tool /4" tool 3/8" tool It is possible to open up the tool slot to 5/8 (16mm) for slightly larger tools. Always remove metal from the top of the slot /8" tool 0.50 center Setting Tools Upside Down The tool blocks have been designed to allow the base of the slot to be raised to ½ center. 1/2" tool upside down This allows any size tool up to 5/8 shank to be mounted upside down to optimize spindle rotation for special needs We do not recommend the use of negative rake insert tools of ¾ center height in these holders. The head extension can cause undue loading. When using negative rake holders, we recommend the axial tool holders that have a fixed center height.

25 22 Gang Tool Machining Advantages Gang tooled lathes provide a reliable, fast method of tooling setup, yet very few operators extract the best from this style of machine and tooling. We hope these pages assist you in optimizing your next set-ups. More Tools on the table When we purchase machine tools, we want the best range of features, at the best price, so we generally buy more than we need, just in case that big job comes in, but we have to make sacrifices for that flexibility. With gang tool lathes that generally means that the larger standard holders are great for that big job, (because the machine manufacturer has to provide for the maximum load that you can put on the tools.) But for the small work, we are always looking for room to load that last tool, This is where you can benefit the most. If you can stack the tools closer together for parts under 1 you can : Get more tools on the plate Change over setups quickly Be more flexible on the small jobs Most turning tools are square shank, but you can get the same results by using boring bars for turning, There are other benefits also, you can cut inside the part and outside with 1 tool, plus a boring bar takes up a lot less room on the tool plate. 2.20" 1.65" You can stack 2 bars back to back for outside turning and threading. Consider that most jobs 1 & under, on a gang tool lathe run up to 3 long, and you can overhang a boring bar 4 times its diameter. A 3/4" boring bar is not over extended for that application. (3/4 x 4 = 3 ) 2.35"

26 23 Multi hole holders When drilling you can use a multi tool holder and stack your drills close together. Combining groups of tools simplifies setup greatly. An NC spot drill (90 O point), a drill, and a tap holder provide an ideal 3 position group for many jobs. Simply swapping a drill and tap and a quick change over is achieved. Ø1.00 When choosing a threading tool, a grooving style holder (Top notch style) can provide a quick change from grooving to threading inserts. Combining turning & grooving bars in a 3 position holder can allow fast rough and finish of the front & back of a part in a small table space. The setup shown requires a spindle direction change, this can be solved by using a left hand boring bar running upside down. Ø " A two position holder is ideal for a simple center drill & drill. The picture shown uses 2 reducer bushings. ER11 or ER16 collet holders offer great flexibility for drill holding.

27 24 Cutoff Tools Cutoff tools for large diameter holders require a deep throat to accommodate 1 diameters, if your part is less than 0.5 diameter a thin grooving insert works well, (Nikcole manufacture a great range of inserts for grooving and turning) Thin Bit also has a wide range of inserts. 1.50" This allows a 5/8 or 3/4" bar for cutoff, saving almost an inch of table space. The boring bar cutoff can also be used in a multi-position holder, 2.30" Longer Parts Sometimes a longer part requires machining using 2 holders, this can be achieved easily. This example shows the ability to turn a longer part, or perhaps a tough material that required more rigid tooling than a boring bar. This setup lends itself to form tooling to decrease cycle times even further. Long Parts Ø " Either tool can be upside down so that a change of spindle direction is not required.

28 25 4, 6, & 8 Position Holders If your parts require frequent repeat setups a large capacity holder can save time and money. Load your tools once in the holder, setup your offsets and at the end remove the tool holder with the tools still mounted. The next time this part is required, simply load the holder onto the plate and locate it against a known stop, Load the offsets from the last time it was setup. And you are ready to run. (On most CNC controls you can download the offsets to a PC or load the offset data in a program that is after the M30 end of program) simply run the stored offset program to load the tool data. This method of setup may seem expensive (saving tools on the shelf) but let us evaluate these numbers: 1 eight position holder = $ tools at $ each = $ Total tool cost = $ If your setup labor rate is $80.00 hour and a new setup takes 2.5 hours typical setup cost is $ A new setup with would cost $ The next setup should take 10 minutes to load the new tool bar and run offset section of program. Saving you $ per setup. Pay back is achieved at 6.4 setups. The more complex the setup the faster the payback time. If a 6 position holder is used payback is even faster (lower holder cost). This example can be used as a basis for your payback time.
